Cấu hình Switch port, VLANs, Trunk, VTP, InterVLAN Routing

10-11-2014, 02:37 PM

Yêu cầu:

Mô hình trên dùng cho 3 nhóm, mỗi nhóm từ 2->3 học viên, thiết bị của mỗi nhóm là 1 router + 3 switch.
Cấu hình trung kế:
1. Cấu hình trung kế Dot1q kết nối giữa Switch – Switch.
2. Cấu hình trung kế Dot1q kết nối giữa Switch – Router.
Cấu hình VTP:
1. Mỗi nhóm cấu hình VTP theo các yêu cầu sau:
2. VTP domain: BCMSNx (x là số thứ tự của nhóm, x = 1,2,3).
3. VTP pass: CISCO (lưu ý chữ hoa chữ thường).
4. SWx1 là VTP server.
5. SWx2, SWx3 là VTP client.
Cấu hình VLANs:
1. Mỗi nhóm tạo 3 VLANs tương ứng với mô hình trên
2. Ví dụ: nhóm 1 tạo VLAN11, VLAN12, VLAN13.
3. Gán port vào VLAN như sau:

Port 1->7 thuộc VLANx1.
Port 10->16 thuộc VLANx2

Port 17->23 thuộc VLANx3

x là số thứ tự của nhóm (x = 1,2,3).

Cấu hình định tuyến giữa các VLAN:
1. Mỗi nhóm cấu hình để 3 VLAN trong mỗi nhóm có thể ping thấy nhau.
2. Mỗi nhóm cấu hình giao thức định tuyến OSPF để tất cả VLAN và Interface Loopback có thể ping thấy nhau.

Gợi ý:
2a: Dùng lệnh sau trên switch trong mode interface:
Switch(config-if)# switchport trunk encapsulation dot1q
Switch(config-if)# switchport mode trunk
!Lưu ý: phải gõ lệnh “switchport trunk encapsulation dot1q” trước lệnh “switchport mode trunk”, nếu gõ theo thứ tự ngược lại sẽ không thể tạo kết nối trung kế thành công
2b: Dùng lệnh sau trên router để cấu hình trung kế dot1q:
Router(config)# interface fastethernet 0/0.11
Router(config-if)# encapsulation dot1q 10
Router(config-if)# ip address 192.168.1.1 255.255.255.0
!lưu ý: câu lệnh trên tạo subinterface f0/0.11, chỉ định encapsulation là dot1q, thuộc VLAN 10 và có IP 192.168.1.1.
3: Dùng lệnh sau để cấu hình VTP:
Switch(config)# vtp domain BCMSN
Switch(config)# vtp mode transparent
Switch(config)# vtp password CISCO
4: Dùng các lệnh sau để cấu hình VLAN:
Switch(config)# vlan 10
Switch(config-vlan)# name VLAN10 !ßđặt tên là VLAN10
Switch(config)# interface range fastethernet 0/1 – 6
Switch(config-if-range)# switchport mode access
Switch(config-if-range)# switchport access vlan 10
